Fresh from introducing its range-topping S-Class Mercedes Benz has followed up with a high performance version.

The new S63 AMG is the most powerful high-performance saloon in the luxury segment, thanks to the 5.5-litre V8 twin turbocharged engine offering up 585 horsepower.

Perhaps more impressive is that the S63 AMG is up to 100 kilograms lighter than its predecessor, and combined with its efficient drivetrain offers combined fuel consumption of 27.4 to 27.9 mpg depending on the model.

Acceleration from 0 to 62 mph takes 4.0 to 4.4 seconds, depending on model variant, and the top speed is electronically limited to 155 mph.

Making its debut at the Frankfurt Motor Show in September, the S63 AMG will go on sale later in 2013.
